Problem 25P
A certain power plant puts out 550 MW of electric power. Estimate the heat discharged per second, assuming that the plant has an efficiency of 38%.
ANSWER:
Solution 25P:
Step 1 of 2:-
Here we need to find the heat discharged per second.
The power plant puts out 550 MW of electric power.
The efficiency of the power plant is 38%.
We know that, the efficiency is
----------------(1)
Where W is the work done and is the heat released from the reservoir at higher temperature.
But we also know that,
--------------------(2)
Where is the heat released from the reservoir at lower temperature.
